Abstract: Due to vast application of wireless sensor network, it has gained popularity among its researcher. The sensors in WSN generate data while it monitors its surrounding area, they perform the data gathering and transmission to the sink node. However, the key challenge is to schedule the node activities for transmission of the data by maintaining the energy consumption. In order to overcome this issue, a cluster based scheduling in WSN is proposed. An energy efficient wake up scheduling algorithm is proposed that support the high data rate transmission and reduces the energy consumption. In this technique, each node wake up only twice that is, once to receive the data from neighbor node and next time to transmit data to sink node. Also, to a Probability-based Prediction and Sleep Scheduling (PPSS) protocol is used to lessen the amount of energy consumption. This is achieved by reducing the number of awakened node in the target vicinity.
